Latest Patents

Yuhmin Lin holds a patent for a "Constant gain and self-calibration technique for RF amplifier." This invention proposes three methods to achieve constant amplifier gain. The methods include on-chip wafer calibration and self-calibration techniques. By automatically adjusting the amplifier bias current, these methods ensure that the amplifier maintains a constant gain despite variations in process, temperature, and supply voltage. Method 1 focuses on maintaining a constant transconductance Gm through wafer calibration. Method 2 utilizes time-domain averaging across different transistors to achieve a constant Gm. Method 3 maintains a constant Gm*R or RF gain by considering the impedance of the RF amplifier's matching network.
